Weight bearing exercise involves placing weight on your feet as you do when walking, stair climbing or jogging. A good strength bearing exercise is weight lifting. If you already have osteopenia or osteoporosis, you should ask your doctor for a referral to a physical therapist. A physical therapist can help you work out an exercise program that is doable, challenging and enjoyable. Planning a program with a physical therapist will also ensure that the exercises will be safe and effective. In addition to building bone and muscle mass, you also need exercises that help balance and coordination.

According to the US Surgeon General's office, men and women between the ages of 19 and 50 require 1,000 milligrams of calcium and 200 IU (International Units) of Vitamin D daily. Those who are past 50 should take 1200 milligrams of calcium daily. Individuals from age 51 to 70 require 400 IU of Vitamin D and those over 70 should have 600 IU. However, more recent research has increased the requirement for Vitamin D to 400 to 800 IU for those under fifty and 800 to 1,000 IU for adults who are fifty years or older. Adults on various medications should also evaluate their prescriptions. Some medications can cause loss of bone mass. Some examples are glucocorticoids and corticosteroids. People also increase their risk for osteoporosis by following an inactive life style. Exercise will build bone density as well as develop muscle strength. When you stress your bones by engaging in physical exercise, the body responds by building new ones. You need to engage in two types of activities: weight bearing exercise and strength bearing exercise.

Since childhood obesity often results in teasing and feelings of low self-esteem, children can worsen the problem by turning to food for 'comfort' as many adults also do. Developing strategies to eliminate childhood obesity, whether it is the result of genes or other factors, will also ensure our children grow up to be healthier, happier adults.

Today, the lives of both children and adults are far more sedentary than they used to be. People now while away many hours watching TV, using the computer and playing electronic games.

Schools are now starting to pay more attention to the problem of childhood obesity. Some schools have banned sodas and chips from their campuses. Many schools have started a "healthy snacks" campaign to educate children to make informed and sensible food choices. Other schools have implemented special physical education programs to provide exercises aimed at weight loss in addition to games such as volleyball and basketball. Health agencies are also targeting parents with educational materials on healthy snacks, proper food portions, counting calories and eating healthy.

In the past, obesity, especially childhood obesity has not received a significant amount of attention from our educational and health agencies. But we now know that obesity is a risk factor for many other diseases such as Type 2 diabetes and many heart ailments.

The World Health Organization reports that 400 million people around the world are classified as obese. Educational and health agencies are also beginning to recognize the increase and seriousness of childhood obesity.

Traditionally, scientists have found an association between FTO and obesity. Other studies have demonstrated that people who have two copies of the obese version of FTO tend to weigh more that those with other versions. These same people are also 70% more likely to be obese.

Wardle stated that she hopes this study will provide researchers new insights into the causes of childhood obesity so scientists and health authorities can work together to develop strategies to deal with the problem.

One direct cause of attention deficit hyperactivity disorder has not been found yet but there are a variety of contributing factors to the development of the condition. Genetic factors include a 75 percent chance that ADHD can develop in twins. Environmental factors include tobacco smoke exposure and alcohol exposure during pregnancy and exposure to lead in the early stages of life. Diet factors include additives such as artificial food coloring. Social factors include relationships with loved ones and other influential people in a person’s life. For instance, if a child has a strong relationship with his or her caregiver then that relationship has a profound effect on the development of the child.

Bipolar disorder is diagnosed in 25 percent of children with ADHD and they display more aggression and behavioral problems that those with ADHD alone. Anxiety disorder is more common in girls that have been diagnosed with ADHD. Obsessive compulsive disorder is thought to share a genetic component with ADHD as they both exhibit some of the same characteristics. People with obsessive compulsive disorder is when people have repetitive mental thoughts that result in compulsive behaviors such as making sure that all the edges of a piece of paper are not rigid but instead smooth.

There are six conditions that are associated with attention deficit hyperactivity disorder. Those six conditions are oppositional defiant disorder, primary disorder of vigilance, mood disorders, bipolar disorder, anxiety disorder and obsessive compulsive disorder. Oppositional defiant disorder is when the patient has anti-social problems such as aggressiveness, temper tantrums, lying, stealing or being stubborn. Primary disorder of vigilance is when the patient has poor attention and concentration. These children also have trouble staying awake. Children with this disorder tend to be hyperactive in order to keep themselves busy and awake. Mood disorders are more commonly seen in boys diagnosed with attention deficit hyperactivity disorder.

The three most common symptoms of attention deficit hyperactivity disorder are impulsiveness, hyperactivity, and inattention. Impulsiveness is acting before thinking about possible consequences, jumping from one activity to another, disorganization and the tendency to interrupt other people’s conversations. Hyperactivity is defined as restlessness, an inability to sit still, fidgeting, squirminess and a restless sleep. Inattention is defined as being easily distracted, day dreaming, not finishing their assigned work in school or at the office and having difficulty listening.
